Internet Draft Test Specs for M3UA Feb 2001
1 Introduction
The M3UA is a protocol for the transport of any SS7 MTP3-User
signaling (e.g. ISUP and SCCP messages) over IP using the Stream
Control Transport Protocol (SCTP) or any other suitable transport
protocol. This protocol would be used between a Signaling Gateway (SG)
and an Application Service Provider (ASP) (e.g. Media Gateway
Controller - MGC) or IP-resident Database.
1.1 Terms Used
Application Server (AS) - A logical entity serving a specific Routing
Key. An example of an Application Server is a virtual switch element
handling all call processing for a unique range of PSTN trunks,
identified by an SS7 DPC/OPC/CIC_range. Another example is a virtual
database element, handling all HLR transactions for a particular SS7
DPC/OPC/SCCP_SSN combination. The AS contains a set of one or more
unique Application Server Processes, of which one or more is normally
actively processing traffic.
Application Server Process (ASP) - A process instance of an Application
Server. An Application Server Process serves as an active or standby
process of an Application Server (e.g., part of a distributed virtual
switch or database element). Examples of ASPs are processes (or process
instances of) MGCs, IP SCPs or IP HLRs. An ASP contains an SCTP
end-point and may be configured to process signaling traffic within
more than one Application server.
Association - An association refers to an SCTP association. The
association provides the transport for the delivery of MTP3-User
protocol data units and M3UA adaptation layer peer messages.
IP Server Process (IPSP) - A process instance of an IP-based
application. An IPSP is essentially the same as an ASP, except that
it uses MU3A in a peer-to-peer fashion. Conceptually, an IPSP does not
use the services of a signalling gateway.
Signalling Gateway Process (SGP) - A process instance of a Signalling
Gateway. It serves as an active, standby or load-sharing process of a
Signalling Gateway.
Signalling Process - A process instance that uses M3UA to communicate
with other signalling process. An ASP, a signalling gateway process
and an IPSP are all signalling processes.

Internet Draft Test Specs for M3UA Feb 2001
Routing Key: At the SG, the Routing Key describes a set of SS7
parameter/parameter-ranges that uniquely defines the range of
signaling traffic configured to be handled by a particular Application
Server. For example, where all traffic directed to a particular SS7
DPC, OPC and ISUP CIC_range(s) or SCCP SSN is to be sent to a
particular Application Server, that SS7 data defines the associated
Routing Key. Routing Keys are mutually exclusive in the sense that a
received SS7 signaling message cannot be directed to more than one
Routing Key. Also, a Routing Key cannot extend across more than a
single SS7 DPC, in order to more easily support SS7 Management
procedures. It is not necessary for the parameter ranges within a
particular Routing Key to be contiguous. For example, an ASP could be
configured to support call processing for multiple ranges of PSTN
trunks that are not represented by contiguous CIC values.
Routing Context : An Application Server Process may be configured to
process traffic within more than one Application Server. In this case,
the Routing Context parameter is exchanged between the SG and the ASP,
identifying the relevant Application Server. From the perspective of
an ASP, the Routing Context uniquely identifies the range of traffic
associated with a particular Application Server, which the ASP is
configured to receive from the SG. There is a 1:1 relationship between
a Routing Context value and a Routing Key at an SG. Therefore the
Routing Context can be viewed as an index into an SG Table containing
the SG Routing Keys.
Fail-over - The capability to re-route signaling traffic as required to
an alternate Application Server Process, or group of ASPs, within an
Application Server in the event of failure or unavailability of a
currently used Application Server Process. Fail-back may apply upon
the return to service of a previously unavailable Application Server
Process.
Signaling Point Management Cluster (SPMC): A complete set of
Application Servers represented to the SS7 network under the same SS7
Point Code. SPMCs are used to sum the availability/congestion/
User_Part status of an SS7 destination point code that is distributed
in the IP domain, for the purpose of supporting MTP3 management
procedures at an SG. In some cases, the SG itself may also be a member
of the SPMC. In this case, the SG availability/congestion/User_Part
status must also be taken into account when considering any supporting
MTP3 management actions.
MTP3-User - Any protocol normally using the services of the SS7 MTP3
(e.g., ISUP, SCCP, TUP, etc.).
Sunil-Prashant-Ashok, HSS [Page 5]
Internet Draft Test Specs for M3UA Feb 2001
Network Appearance: The Network Appearance identifies an SS7 network
context for the purposes of logically separating the signaling traffic
between the SG and the Application Server Processes over a common SCTP
Association. An example is where an SG is logically partitioned to
appear as an element in four separate national SS7 networks. A Network
Appearance implicitly defines the SS7 Point Code(s), Network Indicator
and MTP3 protocol type/variant/version used within a specific SS7
network partition. An physical SS7 route-set or link-set at an SG can
appear in only one network appearance. The Network Appearance is not
globally significant and requires coordination only between the SG and
the ASP.
Network Byte Order: Most significant byte first, a.k.a Big Endian.
Layer Management: Layer Management is a nodal function in an SG or ASP
that handles the inputs and outputs between the M3UA layer and a local
management entity.
Host - The computing platform that the ASP process is running on.
Stream - A stream refers to an SCTP stream.
2 General Principles of M3UA Tests
These tests aim to verify a given implementation of a protocol in
accordance with the relevant draft. The specification is independent of
a given implementation and does not generally imply any modification of
the endpoint under test. However, it is recognized that certain tests
require capabilities of the system that are not explicitly defined in
the draft, and these capabilities may not be present in all
implementations. As a consequence, certain tests may not be possible in
all implementations.
2.1 Presentation of test descriptions
Each test description includes the environment in which the point under
test must be inserted in order to pass the test. Nine test
configurations are defined (named A, B, C, D, E, F, G, H, I and J);
they are presented in clause 3.
Each test is precisely described. Nevertheless, some events not
directly concerning the point under test, or without direct link with
the test nature, are not explicitly described. In order to preserve the
test description implementation independence, certain flexibility has
been left in the test descriptions. This is particularly the case when
it is necessary to terminate the SCTP association (where it is only
mentioned "Terminate" with no more precision). The operator will choose
according to the implementation particularities and the events expected
in the test description, the appropriate Termination means (MML- Man
machine Language, provoked failure, etc.).

Internet Draft Test Specs for M3UA Feb 2001
2.1.1 Pre Test Condition
Before starting the test we need to get the setup into a condition from
where test can be started. These conditions are specified in Pre-Test
condition in each test.
Note: Routing Context and Routing Key has been used inter exchangably.
In case of message it is Routing Context and in the test configuration
it is Routing Key.
Note: Where NIF has been written, it means that NIF+SM. In some
implementation these may be two entities and in some, they may be
implemented in single entity.
3 Test Configurations:
The set of tests described in this Recommendation assumes that the
point under test is inserted in a test environment called "test
configuration".
3.1 Presentation of test configurations:
There are different configurations for testing the M3UA protocol. These
configurations and hence test cases have been divided on the basis of
M3UA at SG and M3UA at AS.

TEST DESCRIPTION:
1. Send ASPAC message with Loadshare mode in type field and Routing
context P from AS to SG for ASP2.
2. Check A: ASP-Active-Ack message should be received at AS.
3. Check B: Traffic should also go ASP2 which has sent the ASPAC. Check
this by sending MTP-Transfer Ind from NIF at SG containing different
CIC values assuming traffic is load shared based on the CIC.
4. Send ASPIA message from ASP1 to the SG.
5. ASP1 will receive ASP-Inactive-Ack from SG.
6. Check that all the traffic is now going to ASP2.
